  #!/usr/bin/env perl

  use strict;
  use warnings;

  if ( 3 == "not a number" ) {
      print "Not a number!";

  Argument "not a number" isn't numeric in numeric eq (==) at test.pl line 6.

If you want a fatal error instead of a warnings:

  use warnings FATAL => 'numeric';

See 'perldoc perllexwarn' for more info.
